I am having great difficulty sourcing the fan though. There are none available in the States. Do you have a source over there?
If you are looking for the original fan (steel blades) fitted to the water pump pulley try an enquiry at
http://www.smallfordspares.co.ukThe fan with plastic blades which fits on the same pulley should probably be available from Melvyn Rutter or the Morgan factory (the one for Ford Crossflows should fit).
For electrical fans look at
